 opposite or alternate leaves; stamens from four to twelve ; pistil 

 always solitary; the stigmas either four or one ; germen inferior in 

 some, superior in others ; seed-vessel for the most part, a capsule 

 usually of four or five cells.

 crenate, permanent. Calyx of one leaf, more or less deeply, four 

 or five cleft; corolla usually monopetalous ; nectaries none, except

 the corolla or twice their number; pistil one, except in royena; 

 germen, in some superior, in others, inferior ; fruit, sometimes a 

 capsule, sometimes a berry ; in each four or five cells ; seeds one 

 or more in each cell, mostly small, chaffy.
